Commands
The commands and data used in serial communication are listed below:
The data comprises read only data (read) and read/write data (read/write). If serial communication is made to write
read only data, the operation will be invalid.
Some of the data are not accessible in some operation modes. If inaccessible data are read out, the read data is
indefinite. If inaccessible data are written, the data is ignored.
When writable data are written in this chip, the built-in register corresponding to each command is rewritten. Then, if
the normal measurement mode is entered, the chip can be operated with the written parameters (mode, etc.). In this
case, because only the built-in register is rewritten, the value in each register returns to its original value (value stored
in EEPROM) when power is turned off and on again.
To store the built-in register value in EEPROM, an EEPROM write command must be received. When an EEPROM
write command is received, the content of the register is stored in EEPROM.
